Apple Video System

Tim Johnson-6
Hello all,

Was there ever code in the Mac OS 8/9 days to handle the Apple Video  
System video input hardware often included on Beige PowerMacs such as  
the 6500/8600/Beige G3?  I'm just looking to grab a frame as a Form.  
Or would this be a job for the OSAPlugin?

Thanks a lot,
Tim

I used to have code that did that. I don't know whether I can dig it out
(definitely can't this week, I'm off to Toronto for the Smalltalk
Solutions conference in an hour) but it's not hard to do -- use FFI to
make calls to Quicktime routines.

I never tried it with Apple video hardware (my beige G3 doesn't have
that option) but the same code worked through a higher-end video input
PCI card system and a FireWire webcam. They used a uniform Quicktime
interface to software, so I imagine the Apple hardware probably did as well.

I'm not sure that I want to dig into QuickTime API under OS 8/9, but thanks for the tip :D.  If I'm feeling particularly rambunctious maybe I'll delve into it.

It is nice to know that it is possible.

Thanks,
